Parade du Danse Macabre

I'm writing a story with this title. I'm trying to write it into a novelette. It starts out with the narrator talking about moving to a new house with her husband when she is pregnant. This is what I have written out so far.

This is what I will write:On the first night at the house--she wakes up in the middle of the night to the sound of marching and horns.She walks up to the window and sees a procession of skeletons with brass instruments.

I'm having trouble linking these two parts of the story together.It should also be noted that these are not the only parts of the story as I have yet to come up with the ending
